To Configure the Quorum Disk on a Two-Host Cluster

If you chose no for Quorum Auto Configuration on a two-host cluster, you must manually select and configure the quorum disk as described in this procedure.

The following sub-steps apply only to a two-host cluster. If you are setting up a three-host or more clustered OTP system, this procedure iis optional.

1. Open a separate terminal window and log in as root to the first OTP host.

2. Type /usr/cluster/bin/scdidadm -L to display the cluster disk information. For example:

   # /usr/cluster/bin/scdidadm -L 1 otpclient1:/dev/rdsk/c0t8d0 /dev/did/rdsk/d1 1 otpclient2:/dev/rdsk/c0t8d0 /dev/did/rdsk/d1 2 otpclient1:/dev/rdsk/c0t9d0 /dev/did/rdsk/d2 2 otpclient2:/dev/rdsk/c0t9d0 /dev/did/rdsk/d2 3 otpclient1:/dev/rdsk/c1t0d0 /dev/did/rdsk/d3 4 otpclient1:/dev/rdsk/c1t1d0 /dev/did/rdsk/d4 5 otpclient2:/dev/rdsk/c1t0d0 /dev/did/rdsk/d5 6 otpclient2:/dev/rdsk/c1t1d0 /dev/did/rdsk/d6

   In the above example, disks d1 and d2 are shared by both hosts of the two-host cluster. The quorum disk must be a shared disk.

3. Configure a quorum disk.

   Type /usr/cluster/bin/scconf -a -q globaldev=shared disk ID where shared disk ID is a shared disk ID. For example:

   # /usr/cluster/bin/scconf -a -q globaldev=d1

4. Type /usr/cluster/bin/scconf -c -q reset to reset the two-host cluster to normal mode.

Next Steps

Create the system shared storage as described in the next procedure.
